CBB-Series
CBB Key Features
CBA utilizes a Lip seal design utilizing a wider contact surface that doubles as a weather seal and pressure seal. There is one
lip seal on each end of the torque shaft.
CBB utilizes a dual o-ring design. There is an o-ring weather seal and o-ring pressures seal on each end of the torque shaft.
There is also a QPQ coated carbon steel washer a protecting the weather seal at each end of the torque shaft. This design
improves pressure seal protection from the elements and separates the pressure seal from the weather seal.

CBA
The housing material and casting are identical between the CBA and CBB.
The CBB housing can not be retrofit with a
CBA torque shaft.
The CBA housing can not be retrofit with a
CBB torque shaft.
The CBB housing is machined differently in
the Torque Shaft opening.
Torque Shaft
The CBB Torque Shaft is machined for the
pressure seal.
The CBA Torque Shaft does not have
a machined groove. It is smooth on the
pressure/weather sealing surface.
Piston
The CBB utilizes the ductile iron piston
as standard. There is not an option for an
aluminum piston. By offering only one style
piston, ordering, filed upgrades, and service
is simplified as there is no requirement
to constantly verify the piston material for
differing service applications.
The CBA options two piston materials. The
standard piston material is aluminum with
an optional ductile iron piston. The high
temperature trim includes a ductile iron
piston by default when a high temperature
trim actuator is ordered from the factory. The
ductile iron piston may be ordered for any
configuration of the actuator. To retrofit a
standard actuator to high temperature trim,
the piston must be upgraded to ductile iron.

Housing seal for Spring Return models, Housing and Cylinder seals for Double Acting
models for both CBA and CBB.
CBB utilizes a thread seal design to ease
Travel Stop setup and increase seal life.
CBA utilizes an o-ring design on the
pressurized Travel Stop.
Jackscrew Seal
CBB utilizes a thread seal design to ease
jackscrew operation and increase seal life
during operation.
CBA utilizes an o-ring design.
Torque Output
An identically sized CBA and CBB actuator will have the same torque outputs.
Operating Pressure
Operating pressures for CBA and CBB are from 40 to 150 PSIG (3 to 10 BAR)
An identically sized CBA and CBB actuator, will maintain the operating pressure ratings,
MAWP, and MSP.
Dimensions
The CBA and CBB have the same dimensions.
Service Kits
CBB service kits will be available on release
of the CBB.
CBA service kits are still available.
The service kits are not interchangeable between the CBA and CBB.
Standard Accessory
Mounting Pad
The CBA and CBB have the same location, size, and bolt holes for the accessory mounting
pad.
Dual Valve Mounting
Interface
The CBA and CBB utilize the same design dual valve mounting interface to permit flexibility
for changing the actuator fail mode, without disassembly, by simply inverting the actuator.
The actuators may be installed in any position; parallel or at right angles to the flow line, in
the vertical or the horizontal plane.
Water Ingress Protection
The CBA and CBB are rated for to IP 66 and IP67M.
Agency Approvals
The CBA and CBB have the same agency approvals.
Lloyds
Atex
ABS
PED 97/23/EC Compliant
Warranty
CBA and CBB have 5 year material and workmanship.
Ordering/Model Designation The difference in ordering a CBA vs a CBB is a change in the third character from an “A” to
a “B”. All other model nomenclature is the same.
